CONDUIT FOR STREET=PIPE.S.

SPECIFICATIQN forming part of Letters Patent No. 285,328, dated September 18, 1883. l

Application filed July 21,1883. (No model.)

To all whom t may concern.-

Beit known that I, ERNEST WENIGMANN, of the cityv of New York, county and State of New York, have invented a new and Improved Conduit for Street-Pipes, of which the following speciiication is a full, clear, and eXact description.

This invention relates to a conduit for receiving mains and pipes in the streets of a city. This conduit will permit ready access to said pipes, and will at the same time present no obstacle to the traffic on the streets.

y The invention consists, principally,in the combination of a conduit having side walls, and caps for protecting the tops of said walls, with cross-pieces and covers, all 'as hereinafter more fully described.

The invention also consists in the details of construction hereinafter set out.

In the accompanying drawings, Figure l is a vertical transverse section of my improved conduit on the line x, Fig. 2. Fig. 2 is a top view of the same; and Fig. 3 a vertical longitudinal section of the same on the line y y, Fig. 1, and z z, Fig. 2.

Similar letters 'of reference indicate corresponding parts in all the iigures.

The letter A represents my improved conduit, which I produce lby digging a trench or ditch along a street, preferably directly at the curbstone. This trench I provide with a proper foundation, a, of brick or other material, and two brick walls or sides, b b. The surface of each wall b is capped by a U-shaped metallic plate, c, having on its outer edge an .upwardly-proj ecting ilange, e. Upon the caps c and between the flanges e rest the covering-plates B of the conduit A. These covering-plates are provided with downwardly-pro- 40 j ecting pins f, which enter perforations in the walls b. Y

g g are cross-pieces stretched across the walls b b at certain regular intervals, and serving to support the ends of the covers B. These cross-pieces are U-shaped in cross-section, Fig.- 3, and are iianged ateach side to support the ends of two adjacent covers, B. By having the cross-pieces g U-shaped the upper surface of the conduit will be practically even, and at the same time the covers B 5o may be readily raised at their edges if access to the conduit is desired.

h is a support extending longitudinally through the conduit A and dividing itfinto two longitudinal compartments. rated near its bottom, Fig. l, to permit the rain-water to ilow from one section into the other. i for the pipes j, which the conduit is to carry.

In order to provide a discharge for the rain- 6o water that may enter the conduit, I connect the latter with the sewers at suitable intervals by pipe 7c. In this pipe I place a iioating check-valve, Z, which permits proper drainage of conduit A, while it will close the passage k, whenever the water in theA sewer rises beyond the valve-seat, by Vlifting and holding the valve against its seat.

I claim as my inventionwalls b b, with the caps c, cross-pieces g, and covers B, substantially as specified.

`2. The combination of conduit A, having walls b b, with the caps c, having flanges e at their outer edges, and with the covers B, substantially as specied. y

3. The combination of conduit A, havingl walls Z), with the caps o, cross-pieces g, and with the covers B, having pins f, that enter perforations in walls b, substantially as herein 8o shown and described.

4i. Ihe combination oi` conduit A, having walls b, with ilanged caps c, and with U- shaped double-flanged cross-pieces g, and with the covers B, substantially as specified.

5. The combination of conduit A, having walls b, with caps c and cross-pieces g, and with perforated longitudinal support 7L and pipe-seats c', substantially as specified.

.6. The combination of conduit A, having 9o walls b, with caps c, cross-pieces g, covers B, and with the pipe 7c and floating check-valve Z, substantially as specied.l
